Slapi_Set_Object_Extension() - Netscape DIRECTORY SERVER 7.0 - PLUG-IN Manual

destructor
objecttype
extensionhandle
Description
When a plug-in is initialized, it must register its object extensions. It must provide
the name of the object to be extended, e.g.,
destructor functions. These functions are called when the object is constructed and
destroyed. The extension functions must allocate some memory and initialize it for
its own use. The registration function will fail if any objects have already been
created; this is why the registration must happen during plug-in initialization. In
return, the plug-in will receive two handles, one for the object type and another one
for the object extension; these only have meaning for the
slapi_get_object_extension()
